The invention provides an automobile diagnosis method and apparatus. The automobile diagnosis method is applied to a cloud server. The diagnosis method comprises the following steps: obtaining vehicle parameter information and a fault type when a fault vehicle generates a fault; according to the fault type, determining a fault diagnosis mode corresponding to the fault type; and according to the vehicle parameter information, performing fault diagnosis by use of the fault diagnosis mode so as to obtain a fault diagnosis result. The automobile diagnosis method and apparatus provided by the embodiments of the invention can realize real-time and rapid diagnosis, does not need manual participation in the diagnosis, saves labor cost, at the same time, can prevent wrong diagnosis caused by insufficient experience of diagnosis personnel, and improves the diagnosis accuracy; and besides, since the diagnosis is performed by use of the corresponding diagnosis mode, external output of core data of an enterprise can be reduced, and technical secrecy work is highly reinforced.
Description
technical field [0001] The invention relates to the technical field of automobile maintenance, in particular to an automobile diagnosis method and device. Background technique [0002] At present, new energy vehicles are still in the initial and rapid development stage, and the reliability of vehicles is not high enough. Especially affected by the stability of key components-battery technology and its management system, reliability problems are mainly reflected in vehicle failures. The existing remote monitoring platform is provided, and the real-time information of the vehicle is sent to the monitoring platform through the vehicle-mounted terminal. Through artificial query on the monitoring platform, the real-time health status and historical data of the vehicle operation can be understood, so it provides a powerful tool for vehicle testing and fault diagnosis. Based on this, it is possible to provide customers with real-time network diagnosis and answering questions. How...
